PHP/XPath: Iterating through ancestor nodes in XML using SimpleXML
- by StackOverflowNewbie
I need to loop through the Ancestors nodes in order to get corresponding BrowseNodeId and Name values. How do I do this using XPath? I'm trying something like the the following, but it's not working:
//BrowseNode[1]//Ancestors[1]/BrowseNode/BrowseNodeId/text()
//BrowseNode[1]//Ancestors[1]/BrowseNode/Name/text()
I think the //Ancestors part of the XPath is actually searching the entire XML tree. What I need to do is visit each node to get the needed values. How do I do this? In the example below, I want: Europe - History - Subjects - Books.
Example XML:
<BrowseNode>
<BrowseNodeId>4952</BrowseNodeId>
<Name>France</Name>
<Ancestors>
<BrowseNode>
<BrowseNodeId>4935</BrowseNodeId>
<Name>Europe</Name>
<Ancestors>
<BrowseNode>
<BrowseNodeId>9</BrowseNodeId>
<Name>History</Name>
<Ancestors>
<BrowseNode>
<BrowseNodeId>1000</BrowseNodeId>
<Name>Subjects</Name>
<IsCategoryRoot>1</IsCategoryRoot>
<Ancestors>
<BrowseNode>
<BrowseNodeId>283155</BrowseNodeId>
<Name>Books</Name>
</BrowseNode>
</Ancestors>
</BrowseNode>
</Ancestors>
</BrowseNode>
</Ancestors>
</BrowseNode>
</Ancestors>
</BrowseNode>
